Vanadium(V) extraction from sulfuric and hydrochloric acid solutions with hydrazides and N′,N′-dialkylhydrazides of Versatic acids

Resumo

Conditions of vanadium(V) extraction from sulfuric and hydrochloric acid solutions with kerosene solutions of hydrazides and N’,N’-dimethylhydrazides derived from fractions of Versatic 10 and Versatic 1519 branched higher carboxylic acids were studied. Conditions of vanadium(V) back extraction from organic phase were studied. For diluted acid solutions, ratios were found to be [V(V)]: [reagent] = 1: 1 and 1: 5 for sulfuric acid media and 1: 1 and 1: 8 for hydrochloric acid media.
